'lhis invention relates to a pleasure swing of the rider-propelled typeintended espe-` cially for use by childrengand therefore designed withparticular attention to ease and safety of operation. It consistsrofcertain elements `and features of construction 1in combination, asherein shown and described and as indicated by theclaims.V

i As shown in the drawings; the'ls'up'poiting frame forthe Aswingvcomprises pests, 1, 1,

disposedin vertical .planesat both sides of the swing` carriage and`sloping upwardlyV and convergentl for qcc'innection with Vhead castings,2-'2 ,w ich in turn are transverselyV joined by a large tubular crossvbar, 3, and a smaller cross bai', 4, as indicatedin Figures 1 and 2.' Ateach side of the frame the head casting, f2, is made'iir twopart's4separable "at the-verticalinedian plane which is common to the crossbars, Bland 4, andthe two fp'arts are clamped together by bolts, 5,t'oetnbrace said cross members, 3 and 4. Oblique braces,

6, extend downwardly andoutiva'ijdly) from the headcastinvs, 2, beingconnected thereto by terminal soc ets, 7 formed withcla'i'nping collars,8,`Which engage the laterally proj ecting endsofl the cross bar, 3. Thesupporting' frame thus 'consists er twej sefeofthreeieeged structuresspaeedfapart Yby the plus elei vertical rplanes er the upf-ightsj, 1,and ned` tegethee by the erase here, Ys 'and e, at their upper ends.Thelower'endsof the post members maybe" anchored in an convenientmanner; they areshown with oo't"`socket"s, 9,whichmay be secured to awooden or Iconcrete flocr or otherwise firmly fastened in the i groundaccording to circumstances' of 1o` cation. The crss bars, Sand 4,- rnaybe off any desired length, as indicated by 4the i broken representationof these parts in Figure, 2; 1n somecases a single set or uprights maysupport two or three swing carriages. To stiften the construction andalso `.'Ilieswingcarriage comprises a seat plank, Y

11, to the underside of which are attached brackets, 12, supporting footboards, 13,v at i each side of the plank, 1l, and tied togetherlaterally by 'cross bars, 14'; sloping braces,-

12, `inay also be providedwat the middle of the carriage. Sloping footrests,f15, are .slidi ably secured to the 4foot boards, 14, by means ofguide stra-ps, 16, and each of them isvad` justable longitudinallybyttheinsertion of a pin," 17, on the underside ofthe foot rest in oneof aseries of holes, 18, inthe foot" board, 13. i

Tofthe upper s'idejof the seat plank,I 11, a rigid frame is securedconsisting of uprights, 20, spaced apart laterally-in pairs, each pairbeing `connected 'toeach other in any suitable manner as by integralVdiagonali portions, 21,

and horizontal bars, 22; the upper ends of the uprights,20,gare formedwith bosses, 25,

'to carry pivot bolts, 26,' by which the rigid carriage structure isattached to hanger bars, yokeS, 28 at.

27 dependent from triangular n tached t'o their upper ends; The uprightsare laterally joined by tie bolts',23, with spacing sleeves,,24,"interpesed' he yokes,` 28,v are fjoju'rnaled on bearing rods,`j29,carriedby the triangular hanger brackets', `1o, .and preferablyantiffrietien rollers`,f30, aref used `at this cnnection as indicated inFigure 6; v f

Tliesvving Acarriage is thus swung from the bearing rods, 20, byparallel hanger bars,y 27,

of exactly equal length with 'the result' thea as the swing travelsAthroughitsratge' of movement the seat plank, 171,1 remains neri,- f

zent-a1' at al1 p'es'itiens, 'as indicated in `decte4 lines in Figure1," and'theangular movement of the hangers, 2i, beat are piveta 2a;takes pleee at a peint fair 'erieugh abdxfe the seat p'lanl, 11, toavoid any danger of striking 'the Heads oftheridef's, a

For operation of the svvingthe hanger bars, 27 are extended Vdownvvardlybelow the pivote; l2e aerei and uieseeepeading p01--` uons are piveeauyconnectent@ la horizontal operating member, 32, with handles, 33,mounted at its ends. The member, 32, remains parallel to the seat plank,ll, throughout the movement of the swing, but moves longitudinally withrespect to the, seat so that as the riders exert pressure or pullhorizontally upon the handles, 33, they tend to move the hangers, 27,away from strictly vertical positions, and thus produce the swingingmotion of the carriage. The member, 32,y consists of two similar halvesseparable at a vertical plane and connected by tie bolts, 34. Pivotsleeves, 35, are secured between the halves of the part, 32, by screws,35, and bushings, 37, carried by the extensions, 31, of the hanger bars,27, provide the pivotal bearings between these parts. To permit ofvarying the leverage. or mechanical advantage of the operating member,32, I prefer to arrange` several bushings, 37, in the lower ends, 31, ofthe hangers, 27, so that the pivot sleeves, 35, may be shifted from oneset of bushings to another when desired. As shown in Figure 5 thepivots, 35, are engaged in the lowest of the three bushings, 37; forconnection with the upper bushings the member, 32, may be turnedupside-down to provide proper clearance of the parts for operation. Thusfor smaller children the member, 32, is connected in the lowestbushings, 37, thus bringing the handles, 33, conveniently near the seatplank, 11, and providing the greatest mechanical advantage in operation,while for larger children the handles, 33, may be raised to a positionfarther from the seat and by connection with one of the upper sets ofbushings, 37, will provide a shorter leverage by which the larger andstronger children can operate the swing with a somewhat shorter workingstroke. y

The sides of the operating member, 32, are fitted between the uprights,20, of the carriage frame with only slight clearance so that there islittle chance that the riders will catch their lingers between theseparts, particularly since there is no occasion for placing the hands onthe portion of the member, 32, which travels back and forth between theuprights, 20. The travel of the member, moreover, is always in adirection perpendicular to the edges of the uprights, 20, so

that there is no wedging or pinching action possible between theseparts.

Owing to the connection of the member, 32, to the lower ends, 3,1, ofthe hangers, 27, the motion of the operating part, 32, is in thesamedirection as that of the swing carriage so that the inertia of anybody movement by 'which the riders accompany their pushing or pullingetforts'on the handles, 33, is added to such efforts and renders theoperation of the swing easier and more natural than if the body motionwere opposite to the direction of swing movement.

A safety feature to prevent'injury to bystanders who might come tooclose to the path of the swing carriage is provided in the form ofrubber armoured buffer wheels or disks, 33, attached to the under sideof the seat plank at each end, preferably on pivots, 39,`which are notrigidly secured to the seat plank but are attached thereto by coiledspring mounting members, 40, so that the buffer wheels, 38, will yieldbodily upon vcolliding with a person 1n the path of the swing and thusavoiding serious injury.

I claim l. In a pleasure swing, the combination of a supporting frame,pivoted hangers depending therefrom in parallel relation, a swingcarriage including a seat and a portion extending rigidly upwardtherefrom having pivotal connection with the hangers, said hangersextending below such pivotal connections, and a horizontally movableoperating member connecting the downwardly extended portions of thehangers.

2. In a pleasure swing, the combination of a supporting frame, pivotedhangers depending therefrom in parallel relation, a. swing carriageincluding a seat and a portion extending rigidly upward' therefromhaving pivotal connection with the hangers, said hangers extending belowsaid pivotal connections, a horizontally movable operating memberdisposed above the plane of the seat and vertically adjustableconnections between said operating member and the downwardly extendingparts of said hangers.

3. In a pleasure swing the combination of a supporting frame, pivotedhangers dcpending therefrom 1n parallel relation, a swing carriageincluding a seat and a portion extending rigidly upward therefromhavinfr pivotal connection with the hangers, a horizontally movableoperating member disposed above the plane of the seat, and connectionsbetween said member and the hangers whereby the movement of theoperating member over the seat is in the same direction as the bodilymovement of the swing carriage with respect to its supporting frame.

4. In a pleasure swing the combination of a supporting frame, pivotedhangers deiending therefrom in parallel relation, a swing carriageincluding a seat plank with foot boards depending therefrom at thesides, longitudinally adjustable foot rest members on said foot boards,a portion extending rigidly upward from the seat plank and havingpivotal connection with the hangers at a distance above the plane of thei seat at the middle of its length, a horizontally movable operatingmember disposed between the plane of the seat and said pivotalconnections, said hangers having portions which extend rigidly downwardbelow said pivotal connections for engagement with said operating memberand handles arranged at opposite ends of said member.

In a pleasure swing, a supporting frame comprising two upright Ysections spaced apart laterally and connected at their upper ends by apair of bars disposed one above the other; a pair of brackets engagingsaid connecting bars and spaced apart thereon within the spacehetweenthe upright sections, a pair of parallel bearing rodshorizontally supported by said brackets spaced apart in the direction ofmovement of the swing, anda swing carriage `with hangers extendingupwardly therefrom pivotally supported by said bearing rods.
